Frequently Asked Questions
Everything you need to know about our functional mushrooms and organic coffee.
What makes Four Sigmatic products different from regular coffee?
Our products combine high-quality organic coffee with functional mushrooms and adaptogens like Lion's Mane, Chaga, and Ashwagandha to provide focus and energy without the typical caffeine jitters or crash.
Will these mushrooms make me hallucinate?
No. We use functional, non-psychoactive mushrooms. They are completely legal, safe, and used for their nutritional benefits rather than recreational effects.
How long does shipping take?
Standard shipping within the United States typically takes 3-7 business days. We also offer expedited shipping options at checkout if you need your mushroom fix sooner.
What is your return policy?
We offer a 120-day 'Money Back Guarantee.' If you are not satisfied with your order for any reason, contact our customer support team and we will make it right.
